In the second quarter of Sunday's loss to the 49ers, Matthews hit Kaepernick well after the San Francisco passer went out of bounds on a third-down play, setting off a scuffle between the teams. Matthews was flagged for a personal foul, but Niners left tackle Joe Staley had an offsetting unsportsmanlike-conduct penalty on the play.

Harbaugh didn't appreciate the "tough talk" coming out of Green Bay, but one week later the 49ers are 1-0, the Packers are winless, and Matthews is down some pocket change on the six-year, $69.73 million contract he signed in April.
